It's the kind of part you find on the transmit side of a flat-panel display link, a camera serial interface, or a backplane data channel inside a server or telecom card.
155 Mbps and the commercial temperature limit
The 155 Mbps data rate is the headline number — it tells you this driver can handle standard LVDS links at the speed of a typical video clock or a fast serial peripheral bus. If your link needs to run faster, you're looking at a different part. No under-hood automotive, no outdoor base station, no freezer storage — the silicon is not characterized for those swings.
That means the factory no longer builds it, and the only channel to get it is the surplus and independent-distribution market. For a new design or a long-term production BOM, you will want a current-production alternative.
